We apply coset codes to adaptive modulation in fading channels. Adaptive modulation is a
powerful technique to improve the energy efficiency and increase the data rate over a fading …

Traditionally, the frequency spectrum is licensed to users by government agencies in a rigid
manner where the licensee has the exclusive right to access the allocated band. Therefore …

While the current generation of mobile and fixed communication networks has been
standardized for mobile broadband services, the next generation is driven by the vision of …

In this correspondence, we investigate the effect of channel estimation error on the capacity
of multiple-input-multiple-output (MIMO) fading channels. We study lower and upper bounds …

Ad hoc wireless networks enable new and exciting applications, but also pose significant
technical challenges. In this article we give a brief overview of ad hoc wireless networks and …

Annotation Deploy and optimize your wireless LAN using the new standard for broadband
wireless communication, OFDM. A comprehensive reference written by two experts who …

Previous studies have shown that single-user systems employing n-element antenna arrays
at both the transmitter and the receiver can achieve a capacity proportional to n, assuming …

We consider three-node wireless relay channels in a Rayleigh-fading environment.
Assuming transmitter channel state information (CSI), we study upper bounds and lower …

In multiaccess wireless systems, dynamic allocation of resources such as transmit power,
bandwidths, and rates is an important means to deal with the time-varying nature of the …

We first study the capacity of Nakagami multipath fading (NMF) channels with an average
power constraint for three power and rate adaptation policies. We obtain closed-form …
